The MB400 by M&B Engineering is a compact 3D video wheel balancer designed for high efficiency in automotive workshops. It features an automatic gauge for precise measurement of wheel distance and diameter, an electric brake to lock the wheel, and a laser line to assist in the application of weights. Equipped with Auto Width technology, it automatically acquires the 3D width of iron rims, and the AutoAdaptive Software recalculates the acceptable unbalance value based on the weight and dimensions of each wheel. This combination ensures optimal performance and minimal vibration, enhancing driving comfort.
